1.1 Important Safety Instructions
The RX-5000AC inverter has been designed and tested strictly according to international safety
regulations. Read all safety instructions carefully prior to any work and always observe them when
working with the inverter.
Incorrect Operation or Work May Cause:
Injury or death to the operator or third party.
Damage to the inverter and other property
or third party.
Safety Instructions
(a) Do not open the case as risk of electric shock
(b) Maintenance should be carried out by a professional licensed technician
(c) Read this manual before operating the system. Redx is not responsible for failure or loss arising
out of improper operation.
(d) All wiring, installation, commissioning, and other work should be done by a licensed technician
(e) Ensure that the storage unit is not installed or used in the following locations:
● Poorly ventilated room
● Places with inflammable gases or corrosive materials and large amounts of dust
●High or low Environment temperature (above 50°C or below -20°C), or high humidity (greater than 90%)
● In direct sunlight or near heating equipment
● Outdoor
● Do not use anything to cover the inlet and exhaust of the module
In case of fire, use dry powder fire extinguishers instead of liquid fire extinguishers.
•
•
All electrical connections are subject to the local grid safety regulations and the storage system should be
reconnected to the grid under conditions of approval.

Table 1-1 - Warnings
Removal of any protection, incorrect use, incorrect installation, or incorrect
operation may result in death/serious personal injury or device damage.
Transportation, loading and unloading, installation, start-up and maintenance
must be carried out by qualified or trained engineer/technician.
Before maintenance or touching any parts, or installation, make sure that the
energy storage unit is disconnected and wait 5 minutes to ensure that the
internal capacitor is discharged.
Installation must be in full compliance with national and local laws and regulations.
Ensure that the system is positioned correctly and is not allowed to roll sideways
or upside down.
Do not change the internal circuit of the machine without permission.
Before connecting to the grid, system the must be connected to the Ground.
Follow the instructions. Improper operation may cause serious damage.
There is a 4G/WIFI device connecting to the inverter, do not place the system
in an environment where there is no 4G/WIFI signal.

The product is not tested to section 5 of AS/NZS 4777.2:2020 and is not to
be used in multiple inverter combinations without additional considerations
by the system designer
The load capacity of the output of the inverter load is as follows:
Inductive load (such as air conditioning, washing machine, motor, etc.).
Single maximum power 3.5kVA, total inductive load maximum power 4.2kVA
(with power grid);
Capacitive load (e.g. computer, switching power supply, etc.).
The maximum power of the total capacitive load is 3.5kVA (without power grid);
The maximum power of the total capacitive load is 4.2KVA (with power grid).

2 Product Introduction
Figure 2.1.1 - The internal system diagram
2.1 System Diagram
RX-5000AC is an AC-coupled inverter. AC-coupled inverter provides advanced storage and
upgrading solutions to the PV grid-connected inverters(any brand or model), enabling the existing
system to benefit from energy storage capability and emergency power supply. The AC-coupled
inverter will detect the energy generated by the grid-connected inverter, which will be used by the
local load first, and the rest will be stored in the battery through the AC-coupled inverter, and the
surplus energy will be fed back to the grid.
Anti-Islanding Protection
The Islanding effect is a special phenomenon when a grid-connected PV system supplies power to
the grid, when the grid has suffered a power loss. Feeding power into a grid during a power loss is
dangerous for maintenance personnel and the public. The RX-5000AC inverter provides Anti-
Islanding Protection to prevent the islanding effect.
